Definitions

• the invention belongs to the technical field of insecticides characterized by surfactants, and in particular relates to an acaricide and application thereof.
• Aphids are arachnids of the arthropods. They are highly diverse in terms of morphological structure, living habits and habitats. They are widely distributed, fast-growing, and capable of parthenogenesis, diverse lifestyles, and environment. Strong adaptability and survival in all kinds of environments ("Apply dropouts", ⁇ , Shanghai: Fudan University Press, 1998, 163-205 pages, public day December 31, 1998).
• locusts can be divided into the following three categories: agroforestry locusts, medical grazing mites and environmental mites.
• Agroforestry aphids include aphids that live on plants and on animal and plant products. They can be divided into herbivorous acarids and carnivorous aphids according to their feeding habits.
• the herbivorous aphids mainly include spider mites, mites, whiteflies, mites, and pupa. Dwarf pampas, leaf scorpion scorpion, Pukou scorpion, root scorpion and formazan, etc., the most harmful to human production, causing human diseases, causing chlorotic spots, causing yellowing and shedding of leaves.
• carnivorous mites mainly include vegetable tanned, long beard, medlar, giant crab, semi-salmon, giant whisker, sucking, carnivorous , velvet mites and large red peony, prey or parasitize other arthropods such as locusts and insects, most of which are biological control factors.
• Medicinal mites refer to all kinds of diseases that cause animal diseases, parasitic and animal feeding, and mites that live in human and animal habitats, such as mites, mites, Demodex, cockroaches, dust mites.

• Environmental mites are mites that are decomposed in the soil. They are mainly mites and white mites. Most of them are rotted and eat on decaying animals and plants. They are important decomposers in the soil ecological environment ( "The latest advances in the study of mites in China", Wumar Abu Limu, et al., Biology Bulletin, Vol. 44, No. 4, 2009, pp. 12-13, open day, December 31, 2009).
• Agroforestry locusts are important pests on agricultural and forestry crops, which occur in the field and cause local disasters. They have become a worldwide problem affecting agricultural production ("The effects of nine pesticides on cucumbers and eggs", Chen Xia et al. Chinese Journal of Biological Control, Vol. 27, No. 1, 2011, 44 pages, public day, February 28, 2011). In some areas where citrus, cotton, vegetables and other crops have been planted for many years, the annual damage is often caused by large-scale production reductions of more than 30%.
• the agroforestry locusts are mainly composed of adult mites and nymphs clustered on the back of the upper leaves of the plants and the central leaves of the central locusts.
• the host leaves are sporadically chlorotic spots, and then the leaves are covered with white or pale spots, which seriously affect the photosynthesis of the crops, destroy the normal physiological functions of the host plants, weaken their growth potential, and lightly drop flowers, drop fruit or Fruit malformation, premature senescence of the plant, a significant reduction in production, and the death of the whole plant, causing serious economic losses.
• the annual losses caused by mites in the world are immeasurable. For example, when cotton seedlings are damaged, they can all fall off, causing light stalks. When the cotton is seriously damaged in the middle and late stages, the number of buds is reduced, the boll opening period is prolonged, cotton production is decreased, and fiber length is shortened.
• the prevention and control of aphids in agriculture mainly adopt chemical chemical control methods, such as ivermectin preparation, pyrethroid preparation, acaricide, chlorpyrifos, bromozide, hydrazine, benzyl benzoate and fumigant. Etc.

Analysis and LSD multiple comparison analysis, the results are shown in Table 4.
• Each processing group of the same vegetable garden treated the plot area of 3 ⁇ 3m 2 , repeated 5 times, taking the average value as the final result, and taking the water as the control; diluting 600 times with 72% frost urea ⁇ manganese zinc for 1 time, 2
• the sub- and three-time treatment groups were separated by an interval of 7 days.
• the acaricide synergist prepared in Examples 1-5 was diluted 3000 times and the agent consisting of 72% frost urea ⁇ manganese zinc diluted 600 times was sprayed once. Each time, the lettuce leaves were uniformly sprayed with wet water as the control, and fresh water was used as the control. After the first spraying, 5 lettuces were randomly selected from each plot, and each plant was examined for 5 leaves from bottom to top. Each leaf was graded according to the percentage of diseased leaf area, and the disease index and control effect were calculated.
• the grading standards are as follows: level 0 is no disease spot; level 1 is the lesion area accounting for less than 5% of the whole leaf area; level 3 is the lesion area accounting for 6%-10% of the whole leaf area; level 5 is the area of the lesion area. The whole leaf area is 11%-25%; the level 7 is the lesion area accounting for 26%-50% of the whole leaf area; the 9th level is the lesion area accounting for more than 50% of the whole leaf area.
• the data were analyzed by ANOVA and LSD multiple comparison analysis using SPSS 19.0. The results are shown in Table 6.
• Example 7 the acaricide prepared in Example 3 was compared with the 1500-fold dilution of the ethoxy-modified trisiloxane and the 1500-fold dilution of sodium dioctyl sulfosuccinate prepared in Example 1.
• the mortality of the 1500-fold dilution and the 3000-fold dilution for 10 minutes and 72 hours of citrus scorpion sputum was significantly improved. It was thus confirmed that the acaricide of the present invention can significantly improve the killing effect.
• Example 1 Number of insects / only Egg number / grain
• the acaricide of Example 1 1200 ⁇ 9.46bB 1.45bB
• the acaricide of Example 2 1200 ⁇ 8.64bB 1.85bB
• the acaricide of Example 3 1200 ⁇ 1.56aA 0.25aA
• the acaricide of Example 4 1200 ⁇ 7.37bB 1.85bB
• the acaricide of Example 5 1200 ⁇ 7.25bB 1.65bB Clear water control 97.5cC 58.8cC
• the acaricide of the present invention has an excellent killing effect on citrus scorpion and its eggs.
